Distance-to-PIM tech based test-gear from
Anritsu for BTS testing
Anritsu Company boasts its newly released Distance-to-PIM
(DTP) technology takes analyzing BTS sites to a new level
by enabling construction crews, technicians and performance
engineers to measure the integrity of both the transmission
system and the surrounding environment for the first time.
Developed as part of Anritsu's recently introduced MW8219A
PIM Master, DTP addresses the growing need to measure Passive
Inter-modulation (PIM) due to the rollout of high-capacity
platforms, such as HSPA+ and LTE.
DTP is said to be superior analysis tool compared to conventional
PIM testers. It encompasses conventional PIM testing theory
but offers users the convenience of distance information
to assist in locating PIM problems. This is a major leap
forward over conventional PIM measurements, and offers information
and clarity never before available. A two-tone test is utilized
and the test signals are stepped to obtain phase information,
which is then processed to display the distance and level
information.
A key advantage of DTP according to Anritsu is that it
allows measurements to be performed through the antenna
system into the surrounding environment resulting in less
crew movement.
With the DTP installed, the MW8219A PIM Master provides
field personnel with a test system that can help ensure
optimum network performance and also locate PIM faults before
inter-modulation distortion adversely affects signal transmission,
says Anritsu.
Field personnel can use the PIM Master to generate two
high-power tones in the transmit band of a base station,
and use any of the handheld analyzers to measure the 3rd,
5th, or 7th order inter-modulation products in the receive
band that travel down the same cable.
The MW8219A can conduct 40 W testing, compared to many
alternative methods that only measure at 20 W, claims Anritsu.
Using double the power allows the PIM Master to locate intermittent
failures due to light corrosion, high-traffic loading, or
changing weather conditions. It also permits users to find
faults in a multi-carrier antenna system or discover microscopic
arcing in connectors.
DTP MW8219A has a Delivery of 10-12 weeks ARO.
